A gambler is deciding whether or not to take a bet. She must pay $40 to take the bet, but if she wins, she will profit $225. The
kicyunya [14]

Answer:

The classification of that same given problem is outlined in the following portion on the clarification.

Step-by-step explanation:

⇒  E[x]=\Sigma_{x=0}^{x} \ x \ f(x)

On putting the values, we get

⇒         =0\times \frac{3}{4}+225\times \frac{1}{4}  -40\times 1

⇒         =\frac{225}{4}-40

On taking L.C.M, we get

⇒         =\frac{225-160}{4}

⇒         =\frac{65}{4}

⇒         =16.25

1...

Whether she wins she would receive $225 with even a 1/4 chance, then she will lose and maybe get $0 with such a 3/4 chance although if she takes a gamble anyway though she will either have to compensate $40 wp 1.

2...

She seems to want the capital to benefit or win.

Ms. Wilson invested ​$34000 in two​ accounts, one yielding 8​% interest and the other yielding 9​%. If she received a total of​
Digiron [165]

Answer:

Amount invested at 8 % rate = x = $ 15000

Amount invested at 9 % rate = 34000 - x = 34000 - 15000 = $ 19000

Step-by-step explanation:

Total Amount = $ 34000

Let amount invested at 8 % rate = x

Amount invested at 9 % rate = $ 34000 - x

Total interest = $ 2910

2910 = \frac{x (8) (1)}{100} + \frac{(34000-x) (9) (1)}{100}

291000 = 8 x + 306000 - 9 x

x = 306000 - 291000

x = 15000

So  amount invested at 8 % rate = x = $ 15000

Amount invested at 9 % rate = 34000 - x = 34000 - 15000 = $ 19000

For each of the described curves, decide if the curve would be more easily given by a polar equation or a Cartesian equation. Th
Reptile [31]

Answer:

  (a)  (x-2)^2 +(y-2)^2 = 16

  (b)  r = 2

Step-by-step explanation:

(a) When the circle is offset from the origin, the equation for the radius gets messy. In general, it will be the root of a quadratic equation in sine and cosine, not easily simplified. The Cartesian equation is easier to write.

  Circle centered at (h, k) with radius r:

  (x -h)^2 +(y -k)^2 = r^2

The given circle is ...

  (x -2)^2 +(y -2)^2 = 16

__

(b) When the circle is centered at the origin, the radius is a constant. The desired circle is most easily written in polar coordinates:

  r = 2
